Answer:
Normal fault
Explanation:
Tensional stress occurs as a result of forces which could be wind, water etc pulling the rocks apart and forming faults. Faults are also known as a type of fracture which occurs between rocks.
Tensional stress along a fault can result in a dropped hanging-wall block relative to the footwall side(in a perpendicular position) thereby producing a normal fault.

From the choices given, an earthquake is the most correct solution.
Earth's inner core is solid even though the temperature is so high because the pressure is also very high.
